Commonly used Kunshan car springs

Usually we are in the evaluation of a car's suspension characteristics, often with "soft" and "hard" to describe, and decided to this feature is mainly determined by the spring and shock absorber, and today take a look at this bounce Jump spring (car interior spring) in the end what is the mystery.

Spring is the elastic element on the suspension of the car, which mainly plays the role of reducing the vibration caused by ground fluctuation, supporting the suspension and enhancing the comfort of the vehicle. If the spring fails, it can cause the center of gravity of the vehicle to shift (some overloaded or older vehicles "collapsed" fall into this category), reduced vehicle maneuverability and reduced comfort.

First appeared, hard-working plate spring

The application of a leaf spring to a car can be very early, and the first Car-made Mercedes built a leaf spring on the rear suspension (the front suspension of this three-wheeler had no spring elements). The simple structure of the leaf spring, combined with its strong bearing capacity and its guiding function (omitted the trailing arm and other components in the suspension), was once widely used in models including cars and trucks.

Due to limited travel, comfort and poor road tracking performance of the current leaf springs in the passenger car has been less and less, and even defensive such off-road vehicles also discarded leaf springs, leaf springs more used in Commercial vehicles, especially trucks.

In addition, there are some special plate springs, such as Corvette composite plate spring above, due to the material properties and layout of the relationship between the ordinary longitudinal leaf spring and the force acting completely different, this is a special case.

Relatively compact structure, the most popular coil spring

Coil springs should now be the most familiar elastic element for everyone, and may be found in many tools or toys. The car is also widely used. Compared with the leaf spring, the coil spring absorbs more energy per unit mass, that is, it achieves the same elastic effect, and its weight is smaller. At the same time, the longitudinal space occupied by the coil spring is also small, which is conducive to the compact structure of the suspension.

Of course, the function of the coil spring is relatively simple, such as no damping effect, you must install the shock absorber, otherwise it will bounce with the elastic ball; In addition, the coil spring can only withstand the vertical force, you must install Guide (such as thrust rod, trailing arm, etc.) to ensure the correct tracking of the suspension.

Due to the compact, easy-to-deploy nature of the coil springs, independent or non-independent suspension, they are widely used in today's passenger cars and, of course, have a large number of retrofit components.
